REPRODUCTION DEVICE, PROGRAM, AND REPRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reproduction device capable of lightening the burden of operations when a person in charge of authoring makes register settings.

SOLUTION: In the reproduction device, an I-Graphics decoder decodes a graphics stream. A transition control unit sets a current button number in a PSR 10 by executing a procedure when device state changes. The procedure includes a determination on whether a button member to enter a selected state as a default setting is determined in default_selected_button_id_ref of page information corresponding to a current page, and when a determination result of the determination is affirmative, the number of the button member determined in default selected button information of the page information corresponding to the current page is set in the PSR 10.
